| Subject: ASoC: wm8903: Fix the bypass to HP/LINEOUT when no DAC or ADC is running |
| |
| From: Alban Bedel <alban.bedel@avionic-design.de> |
| |
| commit f1ca493b0b5e8f42d3b2dc8877860db2983f47b6 upstream. |
| |
| The Charge Pump needs the DSP clock to work properly, without it the |
| bypass to HP/LINEOUT is not working properly. This requirement is not |
| mentioned in the datasheet but has been confirmed by Mark Brown from |
| Wolfson. |
